Question: In an adiabatic expansion of a gas initial and final temperatures are$ T _{1} $ and $ T _{2} $ respectively, then the change in internal energy of the gas is
[MP PET 1997]
Options:
A) Zero
B) ?100 J
C) 200 J
D) 100 J
Show Answer
Answer:
Correct Answer: D
Solution:
For adiabatic process from FLOT $ \Delta W=-\Delta U $
$ (\because \Delta Q=0) $
Therefore $ \Delta W=-(-100)=+100J $
